Bug #70490 [ReO->Ver]: get_browser function is very slow

Edit report at https://bugs.php.net/bug.php?id=70490&edit=1 ID: 70490 Updated by: cmb@php.net Reported by: webtech at mines-telecom dot fr Summary: get_browser function is very slow -Status: Re-Opened +Status: Verified Type: Bug Package: Performance problem Operating System: OS X 10.11.2 PHP Version: 7.0.1 Block user comment: N Private report: N New Comment: I just did some quick measurements with php_browscap.ini (~8.5 MB) looking for one of the first and one of the last entries. Results (in seconds): PHP-5.6: 0.01 resp. 0.62 master: 0.01 resp. 2.98 So, indeed, there is a huge performance *regression*. This doesn't appear to be related to ZendMM, because without it I get similar numbers.
